    I am able to open a web socket connection using wss://servername when running my .NET standard 2.0 plugin within the Unity 2019.2 editor and as an UWP app on Windows 10, but when I try connecting to wss://servername from my XBox One as an UWP app, I get:

    Exception thrown while initializing CommunicationManager: System.AggregateException: One or more errors occurred. ---> System.Net.WebSockets.WebSocketException: Unable to connect to the remote server ---> System.Security.Authentication.AuthenticationException: A call to SSPI failed, see inner exception. ---> Mono.Security.Interface.TlsException: Handshake failed - error code: UNITYTLS_INTERNAL_ERROR, verify result: UNITYTLS_X509VERIFY_FLAG_NOT_TRUSTED

    My guess is this is what happens when your server is using a self signed certificate which the client doesn't know is safe to use.

    yeah the first question to ask is: is it a valid certificate? Meaning one signed by a certification authority? If not that's the problem.

    I put in a SSL certificate signed by a certification authority (SSLS.com) and while I can talk to my service using the UWP app from my laptop, it still throws the same error from XBox One.

    Maybe you should talk to MS support and ask them? I think there could be platform specific restrictions that go beyond the SSL certificate
